W. R. DALES v TOBACCO PIPE Filed. May 25 1923,

WILLIAM R. DALES,

TOBACCO PIPE.

Application filed May 25,

To all whom it may concern:

Be it knownthat' I, iVr-LLIAM R. DALns, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Tobacco Pipe, of which the fol-- lowing is a specification.

This invention relates to tobacco pipes and is designed more especially as arr-"improvement upon the structure disclosed in my copending application No. 625,594, filed Nfarch 21, 1923.

One of the objects of the present invention is to provide a mouth piece formed entirely of a non-flexible material such as silver or other attractive material that is sufliciently serviceable, the construction of the mouth piece being such that, while smoke can be drawn freely into the month, there is no danger of saliva entering the mouth piece through the smoke outlet.

Another object is to provide a mouth piece that can be cleaned readily and, by reason of its sturdy construction, will last indefinitely.

WVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed. without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a side elevation of a tobacco pipe having the present improvements comined therewith.

Fig. 2 is a bottom plan view of the mouth piece and a portion of the stem, the same being on an enlarged scale.

Fig. 3 is a section on line 3 3 Fig. 2.

Referring to the figures by characters of reference 1 designates a tobacco pipe the stem of which has its free end screw threaded as shown at 2 for engagement by one end of the mouth piece constituting the present invention. This month piece is preferably formed of a tube 3 of silver, gold. or any other preferred metal or hard material. This mouth piece is interiorly screw threaded at the stem engaging end, as shown. The other end of the mouth piece is flattened OF NEW YORK, Y.

transversely as shown at4, thereby to provide an upper flat wall 5 and a lower flat wall 6. The upper wall 5 is curved down-- wardly and provides a projecting shield 7 extending the width of the mouth piece. The lower wall 6 is curved and converges toward the wall 5, terminating back from the end of the shield 7 as shown at 8, thereby to provide a very narrow slit or outlet orifice 9' extending the width of the mouth piece. The shield 7 projects below this slit and is designed to prevent the tongue from work ing along the edges of the slit and is also adapted to dissipate the broad thin film of smoke drawn through the slit and into the.

mouth, and to protect the tissues of the mouth. I

Owing to the extreme narrowness of the slit the smoke will issue therethrough at a considerable velocity, thus acting to keep the walls of the slit dry and tending to prevent saliva from flowing back into the mouth piece. pulling ash into the stem and mouth from the bowl. Furthermore as the slit is located at the highest point in the concavity 10- provided under the wall 6 and back of shield 7 it will 'be almost impossible for any saliva to reach the slit. Thus the mouth piece will be kept dry .and clean. Should it be desired to inspect the interior of the mouth piece for the purpose of removing any accumulations that might gather therein, it

would merely be necessary to unscrew the mouth piece from the stem and, because of the comparatively thin walls of the mouth piece and the large opening of passage in the mouth piece, the cleaning operation can be easily performed.

It will be noted that the entire mouth piece is rigid, it being unnecessary to utilize a flexible portion or valve such as heretofore used.

It will be noted that the air suction or pressure in the mouth piece due to the breathing action, will prevent saliva from flowing into the mouth piece while the pipe is being held in the mouth.

What is claimed is 1. A month piece for tobacco pipes comprising a rigid tube having one end portion flattened transversely to provide upper and lower walls extending straight from side to side and converging toward each other along curved lines, the upper wall being spaced from the lower wall at the end of It also prevents the suction from said lower wall by a narrow slit extending the width of the mouth piece, and a shield extending beyond. the end of the lower wall and constituting a continuation of the upper wall, said shield and the lower wall cooperating to produce a transverse concavity under the mouth piece with the slit located in the upper portion thereof.

2. A mouth piece for tobacco pipes formed of non-resilient material and comprising a tube having one end portion pressed together to provide upper and lowe' walls converging along curved lines, and a shield constituting a continuation of the upper wall and projecting outwardly and downwardly beyond the end of the lower wall, there be ing a minute slit formed between the end of the lower wall and the upper wall for the escape of a thin. film of smoke, there being a. transverse concavity formed by the lower wall and shield, the slit being located at the upper portion of the concavity.

3. In a mouth piece for tobacco pipes, non-elastic tube having opposed portions pressed together at one end of the tube to provide a smoke outlet slit extending diametrically across the tube, and a downturned lip extending "from the tube and having its edge located beyond the walls of the slit.

1-. The combination with the stem of a tobacco pipe, of a mouth piece including a nonelastio tube having opposed portions pressed toward each other to provide an elongated smoke outlet slit across the end of the tube and a downturned lip integral with and overhanging said end of the tube, the edge of the lip being located beyond and below the walls of the slit.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of a witness.
